INYHALER.

'SPECIFICATION forming part of Letters Patent N o. 725,928, dated April 21, 1903.

, Application tied Maf 13; 1902.

' the art to which it appertains to make and use the same.

My invention relates to an improvement in inhalers. In the inhaling devices hitherto known to me the construction was such that' the temperature of the vapor could not readily be regulated.

The object of the present invention is tov provide an apparatus whereby the exact regulation of the temperature of the spray ory medicated vapor may be accomplished.

A further object of my invention is to provide a sprayer of such construction that the atomizer will not readily become clogged and in case it does may readily be cleaned.

With these objects in view my invention consists in the features, details of construction,and combination of parts, which will first be described in connection with the accompanying drawings and then particularly pointed out in the claims.

In the drawings, Figure 1 is a longitudinal section of an apparatus embodying my invention; Fig. 2, a front View of the same;v Fig. 3, a plan view; Fig. 4, a detail View, partially in section, of the atomizing device; Fig. 5, a plan view showing said atomizer on a larger scale; Fig. 6, a sectional view, and Fig. 7 end view, of the same, the latter view being partly in section.

Referring to the drawings, and in particular to Figs. l to 3, inclusive, f is a spray-conducting tube, in the presentinstance arranged horizontally and provided at its forward end with a mouthpiece o, the atomizin g device or sprayer a being located at the rear. The said atomizing device leads the medicated fluid from a laterally-arranged vessel c through a small suction-tube b, while the steam or other agent which serves to produce the spray effect is conducted through a supply-tube d.

In order to avoid the accidental stopping or clogging of the suction tube, which so easily occurs in the ordinary atomizer and swarm. 107,155.- (ND modell.)

which can be remedied only with difficulty, I provide a special form of atomizing device, which also prevents the variation or cessation of the spray which frequently occurs in the old forms of atomizers if the small tubes are pushed out of their proper positions. The construction of the atomizing device employed by me will be clear from Figs. 5 to 7. Referring to these views, cis the vessel containing the medicated fluid, said vessel being provided with a laterally-projecting nose or spout in communication with the atomizer of the vessel c. This spout b' has its side Walls arranged in a vertical plane and so close together that the inner space between said side walls is small enough to permit a capillary action to take place in the spout with those fluids which rise by capillary action, which is the class to which belong the medicated fluids employed by me. As a result of this capillary action the medicated fluid is raised in said spout above the level of the fluid in the Vessel c. Upon the outer end of the spout is mounted the nozzle d for steam or other fluid under pressure. When the Asteam escaping from the nozzle d passes over the spout,

it causes the immediate spraying of the medicated fluid, which has been raised to the level of said nozzle by capillary action. Owing to the peculiar form of the spout, the latter does not ,readily become clogged by small particles,las would be the case in an ordinary sprayer; furthermore, if such spout should become clogged it is only necessary to draw a strip of paper or thelike through the spout in order to clear the same.

The conductingtube f is provided with means for admitting the outer air to the interior of the tube, said means preferably consisting of several series of openings j, arranged circu mferentially in rows placed one behind the other at shortv intervals apart. These rows of openings serve to ad mit the outer air to the interior of the conducting-tube. Over the latter is movably mounted a shield 1', whereby the series of openings j may be closed or opened. The position of the shield r may be adjusted with relation to the conducting-tube f in any suitable way. The

preferred method of providing for the ready adjustment of the cylinder or shield r is shown in Figs. 1 to 3, inclusive. In these ICO views the cylinder is shown as provided with a rack-bar 7c, engaged by a pinion m, mounted upon the driving-shaft', journaled upon the. machine-frame, the outer end of said `shaft being provided with suitable means for rotating it in either direction-as, for example, a hand-wheel m'. When the series of openings j are in the rear portion of the tube fat the side of the atomizer, as in the preferred construction shown in the drawings, the said portion of the tube f (which is preferably conical) is provided with a series of funnelshaped ribs g, each rib being located between two rows of openings j. These ribs form entrance-channels for the cylinder 7*, so that the air is allowed to enter the tube f at an incline whose slope is in the direction of the stream or current of spray.

Directly behind the mouthpiece o is mounted a thermometer p, whose lower end projects into the conducting-tube f, whereby the patient may readily read the temperature of the mixture to be inhaled. Vhen the cylinder 'r is moved rearward and the openings j are al1 closed, the spray is insulated from the outer air, so that its temperature at the mouthpiece ois the same as at the atomizerorspraying device. This would give the maximum temperature of the spray. If a lower temperature is desired, it is only `necessary to open a suitable number of rows of openings by the adjustment of the cylinder or shield fr', so that the necessary amount of air is admitted from the outside to the interior of the conducting-tubef,where it unites with the spray, and thus lowers the temperature of the same. From this it will be seen that a rearward movei ment ofthe cylinder or shield r serves to inj crease the temperature of the spray, whilea forward movement of said shield results in af' reduction of the temperature of the spray. In this manner it is possible by this apparatus to i modify the temperature of the spray accord- 1 ing to the desire or according to requirements. l Having thus fully described my invention, 1, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In an inhaling device, the combination, with a mouthpiece, and an atomizing device arranged to deliver aspx-ay to the mouthpiece, of means intermediate the atomizing device and the mouthpiece for supplying a variable amount of temperature-changing iluid to the spray. i

2. In an inhaling device, the combination, with an atomizing device, and a mouthpiece arranged to receive the spray therefrom, of means for conducting the spray from .the atomizing device to the mouthpiece, and means for admitting a variable amount of air to the interior of the conducting means.

3. In an inhaling device, the combination, with a conducting-tube having openings serving to admit the outer air to the interior of said tube, of a mouthpiece at one end of said tube, an atomizer at the other end of said tube, and means for closing the said openings in the tube.

4. In an inhaling device, the combination, with a conducting-tube having a series of openings arranged in circumferential rows, a mouthpiece at one end of said tube, an atomizing device at the other end of said tube, and a shield movable over the rows of openings in the tube.

5. In an inhaling device, the combination, with a conducting-tube having a conicalrear portion provided with openings arranged in rows, a mouthpiece at one end of said tube, and an atomizer at the other end of said tube, of ribs arranged between the rows of openings, and a cylindrical shield movable over the ribs.

6. In an inhaling device, the combination, with a conducting-tube having a conical rear portion provided with openings arranged in rows, a mouthpiece at one end of said tube, and an atomizer at the other end 0 said tube, of ribs arranged between the rows of openings, a cylindrical shield lmovable over the ribs, and mechanism for moving the shield.

7. The combination with a vessel arranged to contain a liquid to be sprayed, of a spout communicating with said vessel and having two side walls closely approaching each other and located in vertical planes, and means for delivering a jet of fluid across said spout.

In testimony whereof I affix my signature in presence of two witnesses.

ANTON BULLING.
